| Popis: | The porphyrin–perylenetetracarboxylic diimide–fullerene triad has been designed to act as an efficient light-to-current converter in molecular devices. Light absorption by the perylenetetracarboxylic diimide–porphyrin dyad occurs in complementary regions, giving extended absorption in the visible light region. This dyad of perylenetetracarboxylic diimide–porphyrin was covalently linked with C60, which can act as an electron acceptor, to construct porphyrin–perylenetetracarboxylic diimide–fullerene (FPP) self-assembled monolayers (SAMs) on the indium tin oxide (ITO) surface. The relative strong photocurrent generation of the ITO/FPP/ methyl viologen (MV2+)/Pt system in the continuous visible light region (from 400 to 650 nm) indicated that this system is highly promising as regards light–energy conversion. |
